Super elements and continuous slabs in Graitec Advance Design 2022

Super element is a compound object created by combining several linear members for design purpose. Among many advantages, the use of a continuous member can be helpful at some locations to obtain better design and detailing of the structure. In fact, continuous members over several spans with same section would increase the design capacity which will result in more economic design and less material cost.

The super element concept is mainly used for steel members. Therefore, the grouped elements must have similarities in term of cross section, angle orientation and material.

1. Advance Design offers different techniques to create the super element:

2. Users can select all the members then right click on the workspace and select create.

3. After selecting the members go to object section and open the super element menu then click on create.

Select the first element and from properties click on the list icon to add more members then press enter to confirm the selection:

 

Consequently, Advance Design will generate the super element with a unique ID and the deflection verification will be accessible from Properties list. This allows the user to configurate and define the assumptions for the code check:Super elements and continuous slabs in Graitec Advance Design 2022 04

Results are obtained by running the analysis, they are accessible from the design result window:

The deflection can be verified for single and continuous members simultaneously:

With the new Advance Design version, the super element concept has been expanded to include concrete objects. Using the above steps, users can now create super element for concrete beams and slabs:

  • The continuous concrete beam can be exported afterward to the Design Module tool and rebars are designed subsequently:

  • Continuous Slabs: Regardless of the geometry of each single element continuous slabs can be generated easily.

  • After running the static analysis, users can launch the Design Modules and FEM results will be exported accordingly:

Two designing methods (FEM based or Strips based) are available for this purposes, other assumptions must be defined to easily calculate reinforcement:

Rebars are automatically placed in order to cover the continuous slab:
